先前研究由二維有限差分軟體（Fast Largragian Analysis of Continua）所建立之數值模型探討加勁擋土結構在不同設計參數下受到動態行為之應力應變。實驗成果顯示增加埋設比與加勁度可提升加勁擋土結構之抗震性。但由於工程上對於加勁擋土結構之穩定分析採用極限帄衡法，故內部之應力應變情形無法分析，在加勁擋土結構設計時僅能採取保守策略。
本研究根據先前研究修正後之數值模型，以真實地震荷重下之情況模擬，探討加勁擋土結構在動態行為下的降伏加速度變化、加勁材的受力情形、規範設計加勁材軸力與模擬之比較及土體之共振頻率。本研究期望經由上述參數之探討，在加勁擋土動態設計施工至完工使用期間，以各階段的變形量預測應力-應變情形分析，進一步改進加勁擋土結構之設計。
研究發現，增加加勁度與埋設比可以減少內部加勁材軸力。另外提高加勁度可以增加模型之共振頻率。根據FHWA（Federal Highway Administration）、NCMA（National Concrete Masonry Association）規範計算之各層軸力與破壞面，顯示規範對於擋土牆之設計太過於保守，且未探討加勁度之影響，故設計上無法充分利用材料之強度。

Previous researches build the numerical models by FLAC (Fast Lagrangian Analysis of Continua) which is a two-dimensional and explicit dynamic finite difference program, to discuss the stress and strain of the dynamic behavior under the situations of different design parameters. Experimental results indicated that when reinforcement length and reinforcement stiffness increased, the seismic resistance of reinforced soil retaining structures also improved. In geotechnical engineering, stability of reinforced soil retaining structures usually adopted Limited Equilibrium Analysis (LEA), so the internal condition of stress and strains could not analysis and the design strategy of reinforced soil retaining structures are conservative.
In this study, the revised numerical model in previous studies is used to discuss the design variables of dynamic loading under real seismic records situations. The variations of yield acceleration, stress situations of reinforcement, resonance frequency of soil, and comparisons of reinforcement axial force between guidelines and simulated model are considered. According to the discussions of the design variables, the deformation analysis of stress-strains situation can be predicted by the variations in the application levels of reinforced soil retaining structures between construction and completion. And the design of the reinforced soil retaining structures can be more completed.
Experimental results demonstrate that internal reinforcement axial force decreases with increasing reinforcement length and increasing stiffness/strength. And resonance frequency of the simulated model increases with increasing reinforcement length and stiffness/strength. According to reinforcement axial force of each layer and failure surfaces which calculated with FHWA and NCMA, reinforcement soil retaining structures designs are too conservative. The guidelines did not consider the effect of stiffness, so the design failed to take full advantage of the strength of materials.
